Read the experiment steps. 1) Put a few drops of iodine solution on a slice of bread. 2) Observe the color change. Which conclusion is the most accurate?

Lütfen önce bir cevap seç.

Doğru cevap: B

Iodine is used to test starch. If starch is present, the color changes to blue-black. So the correct conclusion is that bread contains starch.

A student wants to investigate how light intensity affects photosynthesis. Which setup is the best to keep the test fair?

Lütfen önce bir cevap seç.

Doğru cevap: C

Only one variable (light intensity) should change. Distance from the lamp changes light intensity while other conditions remain constant. This makes the experiment fair.

A student mixes 50 mL of a pH 3 solution with 50 mL of a pH 11 solution. Which prediction is the most reasonable?

Lütfen önce bir cevap seç.

Doğru cevap: A

Mixing an acid and a base leads to neutralization to some extent. Equal volumes do not guarantee exactly pH 7 because concentrations may differ. The safest prediction is that it becomes closer to neutral.

A metal spoon feels colder than a wooden spoon in the same room. Which explanation is the MOST accurate?

Lütfen önce bir cevap seç.

Doğru cevap: D

Both spoons are at room temperature. Metal is a better conductor, so it transfers heat from your hand quickly. That rapid heat loss makes it feel colder.
